I'm working with QuantumGis 1.8 Desktop on Ubuntu 11.10. Two days ago the program crashed while I was working with some WMS layers and then it hasn't been working anymore. When I open QuantumGIS Desktop the program starts, the logo appears but nothing more happens and then Ubuntu suddenly quit the application.
I have tried several times both to remove QuantumGIS and to reinstall it, but the problem remains.
